2.1 Review of Existing Documents

2.1.1 The Contractor is required to provide equipment capable of removing material to be dredged at a rate sufficient to complete the work within the specified time period as indicated in SECTION 00 73 00: Special Contract Requirements.

2.1.2 Offerors are invited to examine Corps of Engineers subsurface exploration logs and to decide for themselves the character of the materials. The subsurface investigation and other reports are available for review at the New York District and some are posted in the FBO with the plans and specifications. For further information bidders should contact the New York District, Engineering Division, Mr. John Cimmino, at (917)-790-8281.

2.1.3 Bidders are expected to examine the site of the work, including the disposal areas, and decide for themselves the site condition that may affect their operations. See Contract Clause entitled "Site Investigation and Conditions Affecting the Work" (Section 00 72 00).

2.2 Existing Conditions

2.2.1 Character of Materials.

2.2.1.1 Subsurface Explorations and tests are provided so that potential bidders can determine the area, extent and characteristics (including dredgeability) of the material to be removed. The results are posted in the FBO site (See ASI Job reports). Although the results of these investigations are believed to be representative of subsurface conditions at their respective locations and for their respective vertical reaches, local variations in the subsurface materials are to be expected.

2.2.1.2 The materials to be found above the required depth, -50.0 ft MLW (plus the Dredge Tolerance 1.0 feet (0.5 feet in area 6),(see plans) include, but are not limited to:

Non-Rock Material

1) Based upon an analysis of sediment samples from the Anchorage Channel Utility Corridor, the grain size characteristics of the proposed dredged material are:

SECTION 35 20 23.00 18 Page 1

9.6% GRAVEL, 76.8% SAND, 9.0% SILT & 4.6% CLAY

Active sand waves are present in the construction area of this contract.

While predominantly sand, some utilities may have also been capped with pea gravel with golf ball and baseball sized gravel at lower elevations.

Offerors are also encouraged to review e4Sciences Report "Anchorage Channel Investigations" dated December 16, 2013.

Holocene (Recent) SAND (SP, SM, SP-SM)- Gray, tan to brown, poorly graded SAND, trace to some fine Gravel, trace to little Silt and Clay. Frequent shells and shell fragments.

Holocene (Recent) SILT and CLAY (ML, CL, OH)- Gray, dark gray to black SILT and CLAY, trace to some Sand and Gravel. Shells and shell fragments are very common.

Trash and Debris

Trash, debris and other miscellaneous man-made and natural organic objects may be encountered during the course of the dredging. This material may be present at any location above the required depth as indicated on drawings.

Man-made materials may include (but are not limited to) wood, sheet metal, glass, lumber, plastics, tires, hoses, chains, cables, and hawsers and abandoned steel pipes. Natural organic objects include wooden objects such as tree branches but does not include inorganic objects such as gravel and large boulders.

Ballast Stone and Ordnance

It is noted that ballast stone and ordnance were found in nearby dredging locations on previous contracts. Rock, rubble, ordnance or other debris may be encountered during the dredging operations; however

Bidders are expected to examine the site of the work and boring samples and decide for themselves the character of the materials

3. Dredging Equipment

3.1 Dredges.

It is anticipated that a variety of dredging equipment will be necessary for the removal of soils/non-rock within the contract area. All material shall be removed with dredging equipment appropriate for the material encountered and location (i.e. clamshell, closed clamshell environmental bucket dredge, dipper, powershovel, water injection, hopper , etc.). The use of cutterhead dredges is prohibited from dredging with surface discharge to the waters of the United States.

The term "container vessel" refers to any vessel used to contain, or hold, dredged material (scow, barge, hopper dredge, etc.). The term "transport vessel" refers to any vessel (tugboat, hopper dredge, work boat, etc.) used to move a container vessel. In the case of a hopper dredge, the hopper dredge may act as both a "container vessel" and a "transport vessel". If hopper dredge engines are not used for propulsion, and another vessel (tugboat, for example) is used to move it, then the hopper dredge would be

SECTION 35 20 23.00 18 Page 2 the "container vessel" and the tugboat would be the "transport vessel".

Vessels Identification and Certification: All vessels(container and transport) that will be used, and/or may be used, during this contract must be identified prior to the first day of physical construction. Vessels identified for use on the contract must be certified to be fully operational, mechanically sound, completely seaworthy, and free of leaks or other defects.

3.1.1 Hopper Dredge Operations

3.1.1.1 When a hopper dredge operation is used, the Contractor will submit daily records of hopper loads, including tonnages of empty and fully loaded conditions prior to pump out. For all types of dredge operations the Contractor will furnish production meter records (using properly calibrated instruments) of suction line densities and pipeline velocities. Production meter records and load meter records must be cataloged either by time of day or load number.

Anchorage Channel was last improved in 1953. Between 1953 and 1973, 4 separate maintenance contracts were issued.

3.1.2 Required Modifications to Hopper Dredges

For this contract Modification to the Hopper Dredges is not required unless unexploded ordnance is encountered then all restrictions and modifications shall be applicable as below and all Ordnance Procedures in the paragraphs below and section 01 35 26 UNEXPLODED EXPLOSIVE ORDNANCE (UXO) OPERATIONS shall be applicable for this contract. The Government reserves the right to issue a contract modification to incorporate the applicable requirements.

UXO Modifications to Hopper Dredges

Based on dredging and test dredging, unexploded ordnance consisting primarily of large caliber projectiles having diameters of three inches or larger, have been found in nearby dredging locations. Because of the danger presented by these objects, dredging equipment utilizing suction heads will have to be equipped with longitudinal bar screens which will have a maximum opening of one and one-half inches between adjacent bars. The screens should be constructed of material that is very durable and wear resistant. The dimensions of the screen bars will be designed and constructed in a manner to maximize the total open area of the suction head through which channel sediments can be dredged and maximize the hydraulic transport efficiency of the draghead. The screens should be constructed whereby the screen bars are in the same plane as the existing lower load bearing surfaces of commonly-used dragheads. This design allows for a self-cleaning type of screen which tends to increase efficiency. During the course of the dredging operation the suction heads and screens shall be inspected on a daily basis to assure that they are functional. If the Contractor proposes the use of dredge plant which utilizes a dredging methodology other than with suction heads, the Contractor will have to demonstrate to the satisfaction of the Contracting Officer, or his representative, that the proposed method will exclude picking up ordnance greater than the one and one-half inch diameter size and passing it through to the area of non-rock placement.

3.1.3 Ordnance Procedures and Reporting Requirements

SECTION 35 20 23.00 18 Page 3

(1) If during the course of the channel dredging, it is observed that any item greater than one and one-half inch diameter is within the hopper, the Contractor will immediately cease the pumping operation, notify the Contracting Officer representative, and inspect the screens on his dredge equipment to determine if a break has occurred.

(2) The Contractor shall prepare and submit a site specific UXO work plan and a safety and health plan to the Government for approval prior to mobilization. The work plan shall contain an UXO operation plan detailing the Contractor's proposed methodology to complete ordnance removal procedures. All UXO related procedures shall comply with CEHND Safety Concepts and Basic Considerations for UXO, 29 June 2001, U.S. Army Corps of Engineers, Huntsville Technical Support Center and Mandatory Center of Expertise for Ordnance and Explosive Waste (Section 01 35 26 and EP 385-1-95a at http://www.hnd.usace.army.mil/oew/techguid.aspx ). The work plan shall describe the qualifications of the UXO personnel. The following are the minimum nonwaiverable qualifications for UXO personnel:

(i) UXO Team Leader (UXO Supervisor): a graduate of the Naval EOC School, Indian Head, MD with at least ten years combined active military EOC and contractor experience.

(ii) UXO Team Member (UXO Specialist): shall have more than three years active duty military EOC experience.

The work plan shall propose an evacuation distance based on the largest piece of UXO expected to be found. The Contractor shall describe feasible alternatives for disposal, and shall recommend the safest and most cost effective method of treatment and disposal of any explosive ordnance and inert ordnance encountered. If on-site detonation is not acceptable, an alternate disposal method should be considered and proposed by the Contractor, and forwarded to the Contracting Officer for approval prior to mobilization.

4. INSPECTORS /INSPECTIONS

INSPECTION (1965 APR OCE)

The plans and specifications establish the contract requirements that the Contractor must comply with. The Corps uses a Quality Assurance/Quality Control management system. The Contractor is responsible for controlling the quality of the work and the Government, in separate but coordinated efforts, assures that the level of quality set by the plans and specifications is achieved.

The inspectors and the Contracting Officer's Representative (COR) at the site of the work have direct and indirect authority to assure that the work is being performed in compliance with the plans and specifications. The inspectors and COR will direct the maintenance of the gauges, ranges, location marks and limit marks in proper order and position. The presence or absence of an inspector shall not relieve the Contractor of responsibility for the proper execution of the work in accordance with the specifications.

The Government and the Contractor both have a role in obtaining quality construction consistent with the contract requirements. On this dredging the following three inspectors are required.

-Government's Quality Assurance Inspectors (QA Inspector) -Contractor's Quality Control Inspectors (CQC Inspector)

SECTION 35 20 23.00 18 Page 4

-Dredged Material Inspectors (DMIs) see SECTION 35 20 23.10 18.

The following summarizes the primary responsibilities of the Contractor's Quality Control Inspectors:

Prior to the start of a project/contract the Government prepares a Quality Assurance Plan which addresses the overall Quality Assurance operations of the field office which is responsible for administering the contract. This plan identifies the Quality Assurance organization and the procedures /methodologies that will be used in carrying out their responsibilities.

Government Quality Assurance Inspectors, headed up by a Resident Engineer, are responsible for carrying out the following Government Quality Assurance responsibilities: (1) establishing construction standards and quality control requirements; (2) maintaining construction management activities, including, among others, checking adequacy of Contractor's control (quality assurance for acceptance), performing specified tests and inspections as designated in the contract, determining that reported construction deficiencies have been corrected; (3) determining payments due to the Contractor; and (4) assuring timely completion.

After the award of the contract, the Contractor prepares a Contractor's Quality Control Plan that identifies their Contractor Quality Control organization and documents the process and methodologies that will be used to accomplish the Contractor's Quality Control responsibilities and ensure that the requirements of the contract are met. Contractor Quality Control Inspectors, headed up by a Contractor Quality Control (CQC) System Manager, are responsible for carrying out the following Contractor's Quality Control responsibilities: (1) producing a quality product on time and in compliance with the terms of the contract; (2) establishing and utilizing a construction quality control program of the scope and character necessary to achieve the quality of construction outlined in the contract; and (3) producing and maintaining acceptable records of its quality control activities.

The Government Quality Assurance inspectors and the Contracting Officer's Representative (COR) have certain direct and indirect authority to assure that the work is being performed in compliance with the plans and specifications. The presence or absence of an inspector shall not relieve the Contractor of responsibility for the proper execution of the work in accordance with the plans and specifications.

The Contracting Officer and the COR reserve the right to have Corps of Engineers and/or the Environmental Protection Agency and the States of New Jersey and/or New York and/or NYCDEP Inspectors accompany all trips to the construction and/or placement site to certify compliance with the requirements of the contract.
